Java .exe files located in System32 a trojan?

Hi everyone,

I got a pop up from the Java updater to get an update but the Vertified Publisher  was "unknown" so I closed the window. Could this have been a fake Java trying to install itself??

 

The files located in the System32 folder are

jaucheck.exe

jucheck.exe

jusched.exe

java.exe

javaw.exe

javaws.exe

 

I also have the first 3 .exe in the Common Files ->Java ->Java Update folder and seaching online ive been reading that those java files in the System32 could be a trojan :smileysad:

 

Any suggestions? I have Windows 7 Running NIS 2011

Thanks.
